My first lab experience in this class made me think about what our class witnessed with the food coloring and water based on temperature. I thought about how the Earth itself has layers. Some things are visible at the top and others are arranged at the bottom. When the Earth first formed it went through the Ice Age. The sun eventually melted the ice and the increase in temperature allowed certain sediments and meteorite compositions to arrange within the Earth, thereby forming the Earth's core, mantle and crust. This change was introduced through random events and therefore the continuous creation of life is a product of randomness. The diversity on Earth that we as humans wish to organize is probably never ending. I think it says more about humanity in terms of our need to find a place for everything and feeling the need to explain it.
